Misery

Misery is a demon horse who loves hanging out in the swamp areas. He hates humans and tries to dispose of them when they are not noticing. He is very hard to tame and he has taken out many humans. You come to the swamp just to explore and see whats in the slimy location. You see him wandering around, walking on the swamp water like a ghost hovering along an invisible path. He notices you and clearly hates you. What will you do? (you can be any gender)
